For a long time, many enterprises only pay attention to profits, turnover and market value. After this epidemic, enterprises, especially private small and medium-sized enterprises, have to pay attention to their own safety and health, such as the health of employees, the safety of production, the safety of capital chain, supply chain and production chain. The outbreak of COVID-19 has brought severe challenges to China's economic development, and the operating environment of private small and medium-sized enterprises has become worse due to the epidemic. How to find opportunities in the crisis is the key to the survival of private small and medium-sized enterprises. In response to the crisis, the human resource management of private small and medium-sized enterprises must be adjusted accordingly to face pressure and challenges. Therefore, from the perspective of enterprise human resources management, the author puts forward the strategies for private small and medium-sized enterprises to cope with the development crisis under the epidemic situation.
This paper studies the construction of modern digital learning platform based on digital media and LTE communication. It provides a new and more effective interaction method for the interaction between teachers and students, students and students, and students and teaching resources through the digital learning platform for digital media technology majors, and also makes the entire education method more efficient. Combining the professional characteristics of digital media technology and the application advantages of digital learning platforms, a systematic explanation of the construction of digital learning platforms for digital media professionals is carried out. Digital media will increase the learning efficiency of digital learning platforms by 6.5%.
The parameter adjustment of PID controller is to determine the best value of three parameter spaces, and the control performance of the system is the best. The education and learning optimization algorithm is a new smart optimization algorithm. In order to strengthen the parameter tuning of PID controller and realize the parameter optimization of PID controller, a self-adjusting method of PID controller parameters is proposed. In order to implement the simulation example using MATLAB, particle swarm optimization algorithm and genetic algorithm based PID parameter adjustment method are compared, the method is simple and high accuracy, PID controller parameter self adjustment, can be quickly and effectively realized.
: Logistics enterprise management is usually managed by information system, which can realize information sharing among customers, logistics enterprises and suppliers, and has great influence on the development of logistics enterprises. With the continuous expansion of economic globalization, the rapid development of high technology and the emergence of third-party logistics with logistics service as its core business, logistics resources have been rationally allocated, and the core competitiveness of manufacturers and logistics providers has also been enhanced. They don't belong to the supply chain of logistics products, but are the third party of transportation, but they serve the supply chain of production films by providing a series of systematic logistics services. The emergence of third-party logistics under cloud computing platform is not only to improve the service level, but also to provide users with better resources through computer system. This paper will analyze and study the third party logistics management mode and its information system based on cloud platform mode, so as to bring certain positive influence for its development.
This paper discusses the urgency and practicability of applying cloud computing to big data in power systems, combining the characteristics of complex power flow calculations and big data applications in power systems, and studying the relationship between power system power flow calculation methods and cloud computing. The important role of cloud computing in power system dispatching, planning, and scientific research is analyzed, and three visualization methods are realized, namely: basic chart visualization, SVG visualization, and map visualization. Among them, for SVG visualization, this paper proposes an SVG visualization display method based on layered thinking.
For traditional vehicle-mounted communication equipment control systems, there have always been problems such as susceptibility to complex environmental interference and poor control accuracy. Propose and design a PLC-based automation control system for vehicle-mounted communication equipment. The system mainly includes automation modules, control modules, and communication modules. The automation module is constructed through PLC technology, and the data attributes are optimized to complete the interaction of data information; the communication signal carrier is debugged according to the information feedback technology, and the multichannel transmission mode is adopted to improve Signal exchange performance up to 9.7%.
